Description

Technical Field

[0001] This utility model relates to the field of disposable hygiene products technology, and particularly to the fields of baby pull-up pants, adult pull-up pants, women's sanitary pants and disposable underwear, especially a shorts-type wearable item. Background Technology

[0002] Disposable hygiene products, such as shorts, generally consist of an outer body and an absorbent core. The outer body is located at the front waist on the side of the wearer's abdomen, at the back on the side of the wearer's back, and at the crotch between the front waist and the back. The absorbent core is fixed to the inner surface of the outer body and extends from the front waist through the crotch to the back.

[0003] The front waist and back typically consist of an outer layer, an inner layer, and multiple elastic threads between them, forming an elastic waistband. In the manufacture of shorts-style garments, to enhance the softness and aesthetics of the elastic waistband, certain areas of the front waist and back are bonded together without adhesive. In these bonded areas, the outer and inner layers are joined together using a hot-pressing process or ultrasonic bonding to create multiple spaced joints, resulting in several regular pleats resembling an accordion on the front waist and back. These pleats are also known as accordion pleats.

[0004] In existing technologies, regular accordion pleats are typically created in the front waist and back by using a hot pressing process (heat sealing bonding process) or an ultrasonic process to join the outer and inner layers together.

[0005] Currently, when the outer and inner layers of the waist and back are joined together using a heat-sealing process (heat-sealing adhesive process) to form multiple spaced joints, the multiple elastic threads sandwiched between the outer and inner layers are in a free state. Only reinforced fixing areas are set at the edges of the side sashes and the edges of the elastic thread cutting areas in the front waist and back to secure the elastic threads. This method has the following problems: When the outer and inner layers are joined together using a heat-sealing process (heat-sealing adhesive process) to form multiple spaced joints, because the elastic threads are in a free state between the outer and inner layers, the areas where the elastic threads form joints between the outer and inner layers are prone to shifting, affecting the formation of regular folds (the folds may sometimes be uneven). This phenomenon is especially pronounced with elastic threads that have weak or thin elasticity. Furthermore, since the elastic threads are free between the outer and inner layers, when the hot pressing process (heat sealing bonding process) is used to join the outer and inner layers to form multiple spaced joints, the elastic threads may move around and cause the spacing between the elastic threads to be too small (e.g., 3mm). This greatly increases the risk of the hot pressing process (heat sealing bonding process) breaking the elastic threads.

[0006] Currently, when the outer and inner layers of the waist and back panels are joined together using ultrasonic technology to form multiple spaced joints, the multiple elastic threads sandwiched between the outer and inner layers are mainly conveyed by the elastic thread guide grooves on the ultrasonic bottom roller pattern. These grooves hold the elastic threads between the outer and inner layers in place. This method has the following problems: When using ultrasonic technology to join the outer and inner layers to form multiple spaced joints, if the elastic thread diameter is large, the elastic thread guide grooves on the ultrasonic bottom roller pattern can hold the elastic thread. However, if the elastic thread diameter is small, the grooves cannot hold it, and the elastic threads still move around in the area where the joints are formed between the outer and inner layers. Furthermore, designing elastic thread guide grooves in the ultrasonic bottom roller pattern increases the design and manufacturing costs of the ultrasonic bottom roller. Furthermore, this technology relies mainly on variations in the diameter of the elastic wire to hold it in place. When using elastic wires of different specifications (thickness), there is a risk that the elastic wire may break or fail to hold properly. In such cases, it is necessary to redesign the ultrasonic bottom roller pattern or replace the entire bottom roller, which greatly reduces the applicability of this technology. Utility Model Content

[0064] Example 1.

[0065] Combination Figures 1 to 10 According to an embodiment of this utility model, a shorts-type garment is provided. For example... Figure 1 As shown, a shorts-type garment includes an outer body 20 and an absorbent body 10. In its unfolded state, the shorts-type garment has mutually orthogonal longitudinal, transverse, and thickness directions. The side in contact with the human body in the thickness direction is the skin side, and the side away from the skin is the non-skin side. Figure 1 and Figure 2 As shown.

[0066] like Figure 1 As shown, along the longitudinal direction, the outer garment 20 has a front waist portion B1 disposed on the abdominal side of the wearer, a back portion B2 disposed on the back side of the wearer, and a crotch portion B3 disposed between the front waist portion B1 and the back portion B2. The absorbent body 10 is fixed to the inner surface of the outer garment 20 and extends from the front waist portion B1 through the crotch portion B3 to the back portion B2.

[0067] like Figure 2 As shown, along the thickness direction, the outer body 20 includes an outer layer 21 and an inner layer 22, which are disposed at least in the front waist region B1 and the rear back region B2. In this embodiment, along the longitudinal direction, the outer layer 21 and the inner layer 22 extend from the front waist region B1 through the crotch region B3 to the rear back region B2.

[0068] The outer sheet 21 is folded over towards the absorbent body 10 to form a folded portion 211, and the folded portion 211 is fixed to at least the inner surface of the inner sheet 22 by the folding and fixing adhesive G5.

[0069] like Figure 1 As shown, the outer garment 20 forms a leg circumference line 20a at the crotch B3, and has side closures 30 on both sides of the front waist B1 and the back B2, so that the shorts-type garment forms a pant shape with one waist opening and two leg openings.

[0070] Specifically, the outer body 20 is folded longitudinally, and the two side edges of the front waist B1 and the back B2 join together to form the side closure 30, so that the shorts-type wearable item forms a waist opening and two leg openings.

[0071] Combination Figure 1 and Figure 2 According to an embodiment of the present invention, along the longitudinal direction, multiple elastic waist lines 23 extending laterally are arranged between the outer layer 21 and the inner layer 22 in the front waist section B1 and the back section B2.

[0072] Combination Figure 1 and Figure 2According to an embodiment of the present invention, in the transverse direction, the front waist portion B1 and the back portion B2 have outer fixing areas C1 on both sides, and a waist extension area C2 is located between the outer fixing areas C1 on both sides. The side sealing portions 30 on both sides of the front waist portion B1 and the back portion B2 at least partially overlap with the outer fixing areas C1, and the two ends of multiple waist elastic lines 23 are fixed in the outer fixing areas C1.

[0073] Along the longitudinal direction, the front waist region B1 and the back region B2 include an upper waist region B11, a middle waist region B12 adjacent to the upper waist region B11 and close to the crotch region B3, and a lower waist region B13 adjacent to the middle waist region B12 and close to the crotch region B3.

[0074] According to an embodiment of the present invention, at least in the upper waist region B11, the outer layer sheet 21 and the inner layer sheet 22 are joined together by an array of multiple joints 40, and there is at least one row of joints 40 between two adjacent waist elastic lines 23 along the longitudinal direction, and the joints 40 and the multiple waist elastic lines 23 are arranged in a staggered manner along the longitudinal direction.

[0075] like Figure 1 and Figure 2 As shown, in this embodiment, in the upper waist region B11 and the middle waist region B12, the outer layer sheet 21 and the inner layer sheet 22 are joined together by an array of multiple joints 40. There is at least one row of joints 40 between two adjacent waist elastic lines 23 along the longitudinal direction. The joints 40 and the multiple waist elastic lines 23 are arranged in a staggered manner along the longitudinal direction. There are no joints 40 in the lower waist region B13.

[0076] Specifically, the outer layer 21 and the inner layer 22 are joined together by means of hot pressing or ultrasonic waves to form multiple spaced joints 40.

[0077] Combination Figures 3 to 6 Multiple joints 40 are arranged in a generally regular column along the longitudinal direction, and multiple joints 40 are arranged in a row along the transverse direction.

[0078] Along the longitudinal direction, each column joint 40 is perpendicular to the transverse direction, or has an angle with the longitudinal direction, the angle being greater than 0° and less than or equal to 15°, or greater than or equal to -15° and less than 0°.

[0079] Along the longitudinal direction, the distance between two adjacent waist elastic lines 23 is a multiple of the distance between two adjacent rows of joints 40. Specifically, let the distance between two adjacent waist elastic lines 23 be b mm, and the distance between two adjacent rows of joints 40 be a mm. The distance between two adjacent waist elastic lines 23 is a multiple of the distance between two adjacent rows of joints 40: b = (1~6)*a, such as b = a, or b = 2a, or b = 3a, or b = 4a, or b = 5a, or b = 6a.

[0080] In some embodiments, the shape of the joint 40 can be a regular or irregular shape such as an ellipse, circle, or strip. In some embodiments, the arrangement of multiple joints 40 along the longitudinal direction can be diagonal, such as... Figures 3 to 5 As shown. In some embodiments, the arrangement of the plurality of joints 40 along the longitudinal direction can be linear, that is, the angle between each column of joints and the longitudinal direction is 0°. In some embodiments, the arrangement of the plurality of joints 40 along the longitudinal direction can also be curved, such as... Figure 6 As shown.

[0081] Specifically, such as Figure 3 As shown, the joint 40 has an elliptical structure in the transverse direction, and there is a row of joints 40 between two adjacent waist elastic lines 23 in the longitudinal direction. Figure 4 and 6 As shown, the joint 40 has a circular structure, with two rows of joints 40 between two adjacent waist elastic lines 23 along the longitudinal direction. Figure 5 As shown, the joint 40 is an elliptical structure along the longitudinal direction, and there are three rows of joints 40 between two adjacent waist elastic lines 23 along the longitudinal direction.

[0082] In this invention, multiple elastic waistlines 23 contract at the front waist (B1) and back (B2), and the outer layer 21 and inner layer 22 form regular accordion pleats M between multiple spaced joints 40, such as... Figure 21 As shown. By having at least one row of joints 40 between two adjacent waist elastic lines 23 along the longitudinal direction, the ratio of the spacing between two adjacent rows of joints 40 along the longitudinal direction to the spacing between adjacent waist elastic lines 23, and the shape and arrangement of the joints 40, the wrinkling effect of the outer body 20 can be optimized.

[0083] According to an embodiment of this utility model, along the longitudinal direction, the longitudinal spacing between two adjacent waist elastic lines 23 in the upper waist region B11 is 2-12 mm, and the linear density of the waist elastic lines 23 is related to the longitudinal spacing as 100-250 dtex / mm. That is, for every 1 mm increase in the longitudinal spacing between two adjacent waist elastic lines 23 in the upper waist region B11, the linear density of the multiple waist elastic lines 23 in the upper waist region B11 increases by 100-250 dtex.

[0084] Along the longitudinal direction, the longitudinal spacing between two adjacent waist elastic lines 23 in the mid-waist region B12 is 2–12 mm, and the linear density of the waist elastic lines 23 is related to the longitudinal spacing as 50–150 dtex / mm. That is, for every 1 mm increase in the longitudinal spacing between two adjacent waist elastic lines 23 in the mid-waist region B12, the linear density of the multiple waist elastic lines 23 in the mid-waist region B12 increases by 50–150 dtex.

[0085] Along the longitudinal direction, the longitudinal spacing between two adjacent waist elastic lines 23 in the lower waist region B13 is 2–12 mm, and the linear density of the waist elastic lines 23 is related to the longitudinal spacing as 50–150 dtex / mm. That is, for every 1 mm increase in the longitudinal spacing between two adjacent waist elastic lines 23 in the lower waist region B13, the linear density of the multiple waist elastic lines 23 in the lower waist region B13 increases by 50–150 dtex.

[0086] Linear density refers to the mass per unit length of fibers, single yarns, netting, ropes, etc., and is an indicator describing the fineness of yarn.

[0087] By considering the relationship between the linear density specifications and longitudinal spacing of the multiple waist elastic lines 23 in the upper waist area B11, middle waist area B12, and lower waist area B13, a better contraction effect can be achieved in the front waist area B1 and the back area B2, thus optimizing the folding effect of the outer body 20.

[0088] like Figure 1 and Figure 2 As shown, according to an embodiment of the present invention, a weakened elastic zone C4 is located between the front waist section B1 and the back section B2 in the transverse direction; inner fixing zones C3 are located on both sides of the weakened elastic zone C4. The ends of multiple waist elastic threads 23 are fixed in the outer fixing zone C1, and the multiple waist elastic threads 23 are cut in the weakened elastic zone C4 and fixed in the inner fixing zone C3. After the multiple waist elastic threads 23 are cut in the weakened elastic zone C4, their elasticity weakens or disappears. In the weakened elastic zone C4, the outer layer sheet 21 and the inner layer sheet 22 are joined together by an array of multiple joints 40.

[0089] Combination Figures 7 to 10 Taking the lumbar region B1 as an example, in the outer fixation area C1, the two ends of multiple lumbar elastic threads 23 are fixed between the outer layer 21 and the inner layer 22 by a first reinforcing adhesive G31, as shown below. Figure 7 and Figure 8 As shown. Here, "fixed" means that the waist elastic line 23 is completely fixed between the outer layer 21 and the inner layer 22.

[0090] In the inner fixing area C3, multiple waist elastic threads 23 are fixed between the outer layer 21 and the inner layer 22 by a second reinforcing adhesive G32, such as Figure 7 and Figure 9 As shown. The "fixed" here also refers to the fact that the waist elastic line 23 is completely fixed between the outer layer 21 and the inner layer 22.

[0091] The first reinforcing adhesive G31 and the second reinforcing adhesive G32 are disposed on the waist elastic line 23, or the first reinforcing adhesive G31 and the second reinforcing adhesive G32 are disposed on the inner surface of the outer layer 21 and / or the inner layer 22.

[0092] Specifically, in this embodiment, in the outer fixing area C1, by coating the inner surface of the inner layer sheet 22 with a first reinforcing adhesive G31, the two ends of multiple waist elastic wires 23 are fixed between the outer layer sheet 21 and the inner layer sheet 22 by the first reinforcing adhesive G31.

[0093] In the inner fixing area C3, multiple waist elastic wires 23 are fixed between the outer layer 21 and the inner layer 22 by applying a second reinforcing adhesive G32 to the inner surface of the inner layer 22.

[0094] In the prior art, in order to form regular accordion pleats between the outer layer 21 and the inner layer 22 at multiple intervals of joint 40, during the process of joining the outer layer 21 and the inner layer 22 together by hot pressing or ultrasonic bonding to form multiple intervals of joint 40, multiple waist elastic threads 23 are in a free state in the area outside the outer fixing area C1 and the inner fixing area C3. However, when the multiple waist elastic threads 23 are in a free state in the area outside the outer fixing area C1 and the inner fixing area C3, during the process of joining the outer layer 21 and the inner layer 22 together by hot pressing or ultrasonic bonding to form multiple intervals of joint 40, the waist elastic threads 23 are prone to shifting between each other in the area where the joint 40 is formed between the outer layer 21 and the inner layer 22, and the waist elastic threads 23 are easily crushed.

[0095] To address the issue of the waist elastic cords 23 shifting between the outer layer 21 and the inner layer 22 during the process of hot pressing or ultrasonic bonding to form multiple spaced joints 40, an embodiment of this invention provides that, in the front waist area B1 and the back area B2, at least in the upper waist region B11, the outer periphery of multiple waist elastic cords 23 is continuously wrapped with a first elastic cord adhesive G1. This allows the multiple waist elastic cords 23 to be auxiliaryly fixed between the outer layer 21 and the inner layer 22 in the waist stretching area C2. The dosage of the first elastic cord adhesive G1 is 0.0015–0.015 g / m / cord. The first elastic cord adhesive G1 overlaps with the first reinforcing adhesive G31 and the second reinforcing adhesive G32, or the first elastic cord adhesive G1 avoids overlap with the first reinforcing adhesive G31 and the second reinforcing adhesive G32.

[0096] Combination Figures 7 to 10Taking the front waist region B1 as an example. In this embodiment, in the upper waist region B11 and the middle waist region B12, the outer periphery of multiple waist elastic threads 23 is continuously wrapped with a first elastic thread adhesive G1, so that the multiple waist elastic threads 23 are assisted in fixing between the outer layer sheet 21 and the inner layer sheet 22 in the waist stretching region C2. The dosage of the first elastic thread adhesive G1 is 0.0015~0.015g / m / thread. The dosage of the first elastic thread adhesive G1 increases with the increase of the linear density of a single waist elastic thread 23. When the linear density of a single waist elastic thread 23 is small (the elastic thread is thinner), the dosage of the first elastic thread adhesive G1 is smaller; when the linear density of a single waist elastic thread 23 is large (the elastic thread is thicker), the dosage of the first elastic thread adhesive G1 is larger.

[0097] In the lower waist region B13, the outer periphery of multiple waist elastic threads 23 is covered with a second elastic thread adhesive G2, and the multiple waist elastic threads 23 are fixed between the outer layer sheet 21 and the inner layer sheet 22 by sheet adhesive G4, as shown. Figure 7 and Figure 10 As shown.

[0098] Specifically, in the lower waist region B13, multiple waist elastic threads 23 are fixed between the outer layer 21 and the inner layer 22 by applying sheet adhesive G4 to the inner surface of the outer layer 21 and / or the inner layer 22.

[0099] The dosage of the second elastic thread adhesive G2 is higher than the dosage of the first elastic thread adhesive G1. Further, the dosage of the second elastic thread adhesive G2 is 0.01 to 0.06 g / m / thread, and the dosage of the first elastic thread adhesive G1 is 0.0015 to 0.015 g / m / thread.

[0100] The dosage of the second elastic thread adhesive G2 in this invention is higher than that of the first elastic thread adhesive G1, making the waist elastic thread 23 of the front waist area B1 and the back B2, at least the upper waist area B11 (in this embodiment, the upper waist area B11 and the middle waist area B12), softer and more comfortable.

[0101] The dosage of the first reinforcing adhesive G31 and the second reinforcing adhesive G32 in this invention is greater than the dosage of the sheet adhesive G4, which prevents the multiple waist elastic lines 23 located in the lower waist area B13 from coming off, and keeps the lower waist area B13 of the front waist B1 and the back B2 in good elasticity.

[0102] In this invention, at least in the upper waist region B11, multiple waist elastic threads 23 are continuously wrapped with a first elastic thread adhesive G1 around their outer periphery. This allows the multiple waist elastic threads 23 to be auxiliaryly fixed between the outer layer 21 and the inner layer 22 in the waist expansion region C2. When the outer layer 21 and the inner layer 22 are joined together to form multiple spaced joints 40, the multiple waist elastic threads 23 are fixed between the outer layer 21 and the inner layer 22. The area where the multiple waist elastic threads 23 form the joints 40 between the outer layer 21 and the inner layer 22 cannot move freely or shift between each other, reducing the risk of the waist elastic threads 23 being broken during ultrasonic or hot pressing processes.

[0103] If the amount of the first elastic thread adhesive G1 continuously wrapped around the outer periphery of the waist elastic thread 23 is too small (e.g., less than 0.0015 g / m / thread), then in areas other than the outer fixing area C1 and the inner fixing area C3, the multiple waist elastic threads 23 cannot be stably fixed between the outer layer 21 and the inner layer 22. In areas where the multiple waist elastic threads 23 form the joint 40 between the outer layer 21 and the inner layer 22, there is still a risk of them shifting or moving freely. If the amount of the first elastic thread adhesive G1 continuously wrapped around the outer periphery of the multiple waist elastic threads 23 is too large (e.g., greater than 0.015 g / m / thread), then in areas other than the outer fixing area C1 and the inner fixing area C3, the outer layer 21 and the inner layer 22 may be mutually bonded and fixed. This results in irregular accordion pleats formed between the multiple spaced joints 40 of the outer layer 21 and the inner layer 22, making the elastic waistband less soft and aesthetically pleasing.

[0104] In this invention, at least in the upper waist region B11 (in this embodiment, the upper waist region B11 and the middle waist region B12), due to the dosage of the first elastic thread adhesive G1 being 0.0015~0.015g / m / thread, in the area other than the outer fixing region C1 and the inner fixing region C3 (waist extension region C2), multiple waist elastic threads 23 can be stably and auxiliaryly fixed between the outer layer sheet 21 and the inner layer sheet 22.

[0105] The auxiliary fixation here is not like that in the outer fixation area C1 and the inner fixation area C3 mentioned above, where the waist elastic cord 23 is completely fixed between the outer layer 21 and the inner layer 22. Instead, it only serves a micro-fixation purpose. The purpose is to prevent the multiple waist elastic cords 23 from moving or shifting freely in the area where the joint 40 is formed between the outer layer 21 and the inner layer 22 during the process of joining the outer layer 21 and the inner layer 22 to form multiple spaced joints 40. This prevents the waist elastic cords 23 from being crushed. At the same time, the first elastic cord adhesive G1 covering the outer periphery of the multiple waist elastic cords 23 will not affect the formation of regular and beautiful accordion pleats M between the outer layer 21 and the inner layer 22. Figure 21 As shown.

[0106] In this invention, because the dosage of the first elastic thread adhesive G1 is 0.0015~0.015g / m / thread, the dosage of the first elastic thread adhesive G1 is very small. During the use of shorts-type clothing (during the repeated stretching and contraction of the front waist B1 and the back B2), at least in the upper waist area B11, the multiple waist elastic threads 23 sandwiched between the outer layer 21 and the inner layer 22 will partially or completely detach from the outer layer 21 and / or the inner layer 22, thereby further ensuring that the outer layer 21 and the inner layer 22 form regular and beautiful accordion pleats M between the multiple spaced joints 40.

[0107] Combination Figures 7 to 10 According to an embodiment of the present invention, the elastic weakening zone C4 located in the front waist B1 extends longitudinally to the crotch B3. In the crotch B3 near the front waist B1, multiple abdominal elastic lines 24 extending laterally are arranged.

[0108] Multiple abdominal elastic sutures 24 are severed in the area of ​​weakened elasticity C4 and fixed in the fixation area C3 inside the area of ​​weakened elasticity C4. After the multiple abdominal elastic sutures 24 are severed in the area of ​​weakened elasticity C4, their elasticity is weakened or disappears.

[0109] like Figure 7 and Figure 9 As shown, in the inner fixation area C3 of the elastic weakening area C4, multiple abdominal elastic sutures 24 are fixed between the outer layer 21 and the inner layer 22 by a second reinforcing adhesive G32. Specifically, in the inner fixation area C3, multiple abdominal elastic sutures 24 are fixed between the outer layer 21 and the inner layer 22 by applying the second reinforcing adhesive G32 to the inner layer 22.

[0110] like Figure 7 and Figure 10 As shown, the periphery of multiple abdominal elastic threads 24 is covered with a second elastic thread adhesive G2; at the crotch B3, the outer layer 21 and the inner layer 22 are fixed by a sheet adhesive G4, and the multiple abdominal elastic threads 24 are fixed between the outer layer 21 and the inner layer 22 by the sheet adhesive G4.

[0111] The dosage of the second reinforcing adhesive G32 in this invention is greater than the dosage of the sheet adhesive G4, which prevents the multiple abdominal elastic threads 24 at the crotch area B3 near the front waist B1 from slipping off, so that the crotch area B3 near the front waist B11 maintains good elasticity and improves the wrapping effect of the crotch area B3.

[0112] like Figure 1As shown, according to an embodiment of the present invention, in the crotch area B3, multiple elastic lines 25 extending along the contour curve of the leg are arranged between the outer layer 21 and the inner layer 22. The multiple elastic lines 25 extend from the crotch area B3 along the contour curve of the leg to the front waist area B1 and the back area B2.

[0113] The front waist area B1 and the back area B2 have lateral fixation zones C1 on both sides. In the lateral fixation zones C1, the ends of multiple leg elastic threads 25 are fixed between the outer layer 21 and the inner layer 22 by a first reinforcing adhesive G31. Figure 7 and Figure 8 As shown.

[0114] At the crotch area B3, the outer layer 21 and the inner layer 22 are fixed together by sheet adhesive G4, and multiple leg elastic threads 25 are fixed between the outer layer 21 and the inner layer 22 by sheet adhesive G4. Figure 7 and Figure 10 As shown.
